CAPPED-HUB MINE-CAR WHEEL.

Patented Oct. 3,1916.

Application led November 22, 1915. Serial No. 62,891.

Be it known that I, ERNEST M. HICKS, residing at Berwick, Pennsylvania, and being a citizen of the UnitedStates, have invented certain new and useful Improvements in Gapped-Hub Mine-Car lVheels, of

which. the 'following is a full, clear, andi exact description. such as will enable others skilled in the art to which it appertains to make and to use the same, reference being had to the accompanying dra-wings, which illustrate the preferred forni of the invention, though itis to he understood thatthe invention isnot limited to the exact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

In said drawings: Figure 1 is an elevational view of the improved wheel hereinafter described. Fig. 2 is a vertical sectional view. the section being taken on line 2-2 of Fig. l. Fig. 3 is an elevational view' of the hub cap hereinafter described. Fig. f1 is a plan view' of said hub cap. Fig; 5 1s an enlarged fragmentary detail view. Fig. 6 is a sectional view, the section being taken on line 6 6 of Fig. 1, showing how the hub cap'is locked in position; and Fig. 7 is a sectional view taken on the same line W1th the lug of the hub cap and the key employed to lock said hub in position, both removed. The *object of the invention is to provide a simple'form of mine car wheel ofthe selflubricating type which is composed of parts which may be assembled where used and, when-once assembled, will notv require disassembling until it becomes necessary to remove the wheel from the, axle upon which it is secured for service.

A feature of advantage is that but a small amount of machine work is necessary in the fabrication of the wheel and its associate partsand thereby the cost ofmanufacture is reduced to a minimum.

Another advantage is that the wheel may be used on either a straight axle, that is, an axle of uniform `diameter-,from end to end, or on axles which have a portion of their ends of `reduced diameter.

Other features of advantage will be apparent from thefollowing description.

Referring particularl to the parts, 8 1ndicates generally the ub portion of the Wheel which is provided with anvoil chamber 9, adapted to contain oil or other'suitable lubricant, .which may nd its way through orifices 10 to the axle 11, the lubricant being inserted through the lubricant valve-13 inserted in the face of the hub as now common in this type of wheel.

'T he hub portion of the wheel is provided with an inwardly extending sleeve 11, which 1s adapted to enter a journal box-not shown-which journal box is commonly employed in this type of construction andV is secured to one of the'sills or to some other convenient part 'of the car. Extending outwardly from the face of the hub 8, are shouldered portions 15 which, v as will be noted in Figs. 6 and 7, are each provided with an enlarged opening 16 at one side and with a stop wall 17 at the opposite side, a passage 18 being provided through said wall 17 for the reception of a locking key hereinafter referred to. Any number of parts 15 may be provided, though three have been found to be sufficient' and three only are illustrated.

The hub cap 20 is provided with wedge shaped lugs 21 corresponding in number and spacing to the parts 15 just referred to, said lugs being of such sectional area that they will readily pass into openings 16 and leave a space for the passage of the locking keys 22 as shown in Fig. .6 when the hub cap has been partially rotated to insert the lugs 21 in the openings 16 in contact with the walls 17 before-indicated. After the lugs .have been thus positioned, keys 22 are inserted, driven home andthe ,reduced end portions 23 Aare upset as shown inlFig. 6, thereby securing the locking keys 22 in position and, due to the coincidence of thein-. clined faces 21 of the locking keys 22 and the inclined faces 25 of the lugs 21, the lugs 21 will be securely locked in position by said-keys, thereby securing the hub cap- 20 M to the wheel hub 8.

As the lubricant has a tendency to'l find its way through the outer face of the` hub, it is preferred that a .washer 30 be interposed between the hub Sand the .hub cap 20, Which-Washer may be and preferably is a compressible material into which the perimetrical portion of the4 hub cap shall 'be seated when the keys 22 are driven home as before indicated thereby preventing a loss of lubricant from the interior of the hub of the Wheel. v

In the form of construction shown a cap i upon partial rotation of Washer 33 is slippedvover the reduced end portion 11a of the axle and said cap washer in the barrel portion of the Washer 33 and the reduced end of the axle 118.

I'Vhat I claim is:

1. The combination in a Wheel, of a fixed hub and rim portion provided with shouldered portions projecting longitudinally of the hub and a hub-cap'adapted to rotatably interlock with said shouldered portions.

2. In a car Wheel, a hollow hub portion with integral perforated lugs outstanding therefrom, a hub-cap adapted to interlock with said lugs upon partial rotation thereot` and means interlocking with said hub-cap and lugs to lock said hub-cap in position.

3. 'In-a car wheel, a hub portion and a hub-cap each being provided with outstanding portions adapted to interlock with coincident outstanding portions on the other said hub-cap and flexible locking means therefor.

4. The combination in a Wheel, of a cast hub provided with shouldered portions extending beyond its `outer face, a hub cap provided with lugs adapted to register with said shouldered portions, a compress'ible @opten or? this patent may te obtained for tive cente each, by. addressing the washer interposed between the wheeftl hub and said hub cap., and means adap ed to 'time'force the hub cap into engagement with said Washer.

6. The combination in a mine car wheel, of a cast rim and a hub portion, the latter being provided with outstanding shouldered portions, a hub cap having lugs thereon adapted to register with said shouldered portions, and locking keys adapted to-engage the shouldered portions of the hub and the lugs on the hub cap to secure the latter in position.

In witness whereof I hai'e hereunto Set my hand inthe presence of two witnesses.
